The postantibiotic effect (PAE) of trovafloxacin (CP 99,219) was investigated with six strains of Pseudomonas aeruginosa at concentrations equivalent to 0.5, 1, 2 and 4 x MIC. Trovafloxacin exhibited a significant PAE with four out of the six strains of P. aeruginosa studied. The PAE values obtained for trovafloxacin with P. aeruginosa ranged from 0.3 h to 2.3 h, increasing with increased exposure time and trovafloxacin concentration.
